This will install my patched kernel together with the required wifi firmware. As it is a patched kernel it means it will not get any automatic updates from Canonical so it should only be used for testing purposes. Currently only Intel Compute Sticks are supported.

It is also still in development and as everything is extremely new not everything has been exhaustively tested so your feedback is appreciated.

Credit goes to Pierre-Louis Bossart for the original HDMI audio patches which I've backported to the current 'xenial' kernel and to Bastien Nocera (hadess) for the wifi source.

I'm currently testing on the Intel Compute Sticks (Baytrail Z3735F & Cherrytrail x5-Z8300). Feedback and/or "level of interest" will determine whether it is worthwhile investing any further effort into this.

Hey, is there any chance of the patched kernel working on an Acer Switch 10V (SW05-14)? It has the same Cherry Trail CPU, x5-z8300. Works almost flawlessly other than WiFi, Sound and battery indicator (shows up as power supply).

Would there be any universal solution for the Baytrail tablet "Black screen on boot" issue. Tried all sorts of things from:http://florian-berger.de/en/articles/i915-black-screen-on-boot-issue/http://askubuntu.com/questions/136593/how-can-i-fix-broken-i915-drivers-for-intel-gpushttps://wiki.ubuntu.com/Kernel/Debugging/Backlighthttp://ubuntuforums.org/showthread.php?t=1744809etc etcbut it seems that only "nomodeset" can produce output on internal display (800x600).One possibly interesting thing that I came across when I boot with "nomodeset" might be that the command "lshw -C video" produces output which apart from other stuff indicates "width: 32 bits" even though I boot a 64bit operating system. Of course it is 32bit UEFI and boot involves "bootia32.efi". Apologies if this is irrelevant, I am only a hobbyist and a poor amateur:). Thanks

just had something similar an hour ago. pressed esc on booting, advanced options, booted into recovery on earliest kernel, chose safe graphics mode, used synaptic to fix broken packages. then shutdown. then booted that kernel normally. the rest depends, i guess

Hi Ian, I am working on XJUbunTAB and your work is very useful. I think that we can all benefit from sharing knowledge between tablets and miniPCs users with Intel Atom CPUshttp://techtablets.com/forum/topic/linux-on-atom-based-devices/

Then can you reupload the patch so we can use the fix on other devices than your small list of compute sticks? Or your kernel .debs? I've got a Z3735-based minipc that I'm tinkering with to get HDMI audio working and the ISO is giving me the blackscreen on boot issue mentioned above.

Can you send me the patched kernel (deb) for install in my custom 16.04? I have an imagen with aaaaall the system (Ubuntu 16.04) configured, with a lots of programs, emulators, etc., and I can't spend time again to configure all with your ISO.

Furthermore If I try to patch de kernel (http://www.cnx-software.com/2016/05/26/updating-star-cloud-pcg02u-to-ubuntu-16-04-with-wifi-and-hdmi-audio-support/) finally I had an error :(
